The G7 is an informal bloc of seven advanced industrialised democracies – the U.S., Canada, France, Germany, Italy, Japan, and the U.K – and the European Union as a non-enumerated member'. Owing to its informality, the G7 has claimed a number of accomplishments. This practical case describes the decision-making processes and two concrete outcomes of the 2021 G7 Summit held in Cornwall, UK: the $600 bn plan for a major global infrastructure program to counter China's Belt & Road initiative; and the agreement to overhaul the global corporate taxation rules and to back a global minimum corporate tax of at least 15%. The case is narrated from the perspective of an OECD Sherpa – an official in charge of all the preparation and agenda-setting of the event who accompanies a leader to the summit and ensures that its objectives are achieved through negotiation. The case allows a better understanding of the importance of agenda coordination at a major global governance forum like the G7 on two major topical issues: the feasibility of a significant infrastructure plan and its effect on the relations with a major emerging power like China and supporting a global minimum tax rate that could ensure vital additional revenue to governments.
